It is different from other application lockers in that it requires zero permissions to run. PadLock does not collect any information. It only has permission to use In-App Billing services and run the Accessibility Service which monitors the various applications to lock them.
PadLock is proud to be:
• Lightweight with few permissions.
• Completely free and open source.
• Simple and easy to use.
• More reliable than other application lockers at correctly securing your device.
PadLock is developed in the open on GitHub at: https://github.com/pyamsoft/padlock
The entire source code of the application is available. If you know a few things about Android programming and are wanting to help out with development you can do so by creating issue tickets to squash bugs, and propose feature requests for future inclusion.
